Problem Description

This is how my spyder looked before updating to 5.3

Here is a generated image

This is what the text looks like, you can see each line is perfect no overlap.

This is what I get now after updating to 5.3. Same setting but icons and taskbars are huge, text is use, the icons are blurry

Here is the same image generated, but not its really blurry

I can toggle/lower the text size but this does noting for the huge panels and blurriness.

You also note, when I highlight a line of text, as in line 6, the number overlaps. I'm not sure how to fix this issue

Things I've done to help

1. So far I reverted to conda install --revision=9 this doesn't help
2. Restarted my device
3. I've noted in another environment which I have not updated spyder (the one i used to generate the images above) everything looks fine.

Hey @julie-jch, thanks for reporting. You said:

I think the size of icons and toolbars is the right one, specially compared to the font size you're using in the editor. As a comparison, this is how Spyder looks for me (on Linux too):

On this screenshot is specially clear that icons were way too small for you before:

Here is a generated image

We didn't design Spyder to look like that, so we're not planning to change it, sorry. Again, this is how it looks for me:

I think it's really close to your 5.3 screenshot

Here is the same image generated, but not its really blurry

However, you're correct that some icons are blurry. Thanks for pointing that out (we didn't notice it because we don't develop on 4k/8k monitors).

We'll fix that problem in our next version (5.4.0), to be released next month.

Sorry, I missed these comments of yours:

I can reproduce this error with the elusiveicons font you're using:

@impact27, could you take a look at it? I thought it was fixed, but it seems it's still an issue for some fonts.

@julie-jch, the solution for now is to use a different font (e.g. Ubunto Mono).

I can't reproduce this with elusiveicons on mac. The numbers are not well aligned because this is not a monospaced font, but the highlighting puts the number at the correct position.

Ok, thanks a lot for checking this so quickly. I didn't know elusiveicons is not a monospaced font (although Qt detects it as such). Any idea if there's a way to improve that?

[impact27]

This is what I have with elusiveicons: We could remove it from the list of options maybe?

We could remove it from the list of options maybe?

That's a good idea but it doesn't seem easy or even possible. So, let's leave it like that.

Thank you. One thing I noticed that may be informative, I have a text scaling factor of 1.9 in my font settings [Linux Mint system] (without this, the linux system text is very tiny). When I set this factor to 1, it looks much better, I don't experience the overlapping text, images in the plots pane are no longer blurry. So maybe its some incompatibility between the UI and this setting.

Thanks for letting us know about that @julie-jch. There's little we can do about it though because this is a very specific use case and we have a lot of other things to address.
